DIY TB3 eGPU + RTX3060 Ti
I just built my own eGPU case and wanted to share my experience:
- WAVLINK Thunderbolt 3 to NGFF NVMe PCI-E (~120€)
- ADT-Link R43SG PCI-E to NVMe Adapter (~45€)
- AORUS GeForce RTX™ 3060 Ti MASTER 8G (~600€)
- Some BeQuiet ATX power supply (550W)
- My DIY-Case (~25€ for the wood only - you will still need some glue, tools and screws)
In total thats around 190€ for the case + whatever for your graphic card
Note: Prices do vary a lot depending on your country/the shop (you may find cheaper ones on aliexpress)
Building the case is pretty straightforward if you have some experience with processing wood.
After I connected everything, I was surprised, that everything worked right out of the box, I only had to reinstall my Nvidia drivers with the card connected, so that my computer could identify the RTX3060Ti (My laptop has an inbuilt graphics card - thats why i had to reinstall it instead of install).
Now I want to share with you my benchmarks. I made them rather quickly, thats why there is some fluctuation between the tests.
My Laptop Specs:
- HP Spectre x360 fl1015ng (2019)
- Intel i7-9750H
- Internal graphics: Intel UHD Graphics 630
- 2. Internal graphics: Nvidia GTX 1650 (Mobile Max-Q)
I made the benchmarks (userbenchmark.com) with the following configurations:
- Using the internal Intel GPU
- Using the internal Nvidia GTX 1650 Max-Q
- Using the external RTX3060Ti with the laptop-screen
- Using the external RTX3060Ti with an external monitor connected to the GPU
It surprised my that I can reach almost the average performance of an RTX3060Ti with an external monitor (128% of avg. 132%)
And also if i'm using the laptop monitor, the GPU bench is 108%, which is about 19% performance drop compared to the average.
What do you think?
